Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Phenytoin stabilizes neuronal membranes by promoting voltage-gated sodium channel inactivation, reducing high-frequency neuronal firing and seizure propagation.
Selective serotonin reuptake inhibitor (SSRI); potentiates serotonergic activity in the CNS by inhibiting presynaptic serotonin reuptake.
300-400 mg per day orally in divided doses (e.g., 100 mg three times daily); loading dose 1 g orally divided into three doses given at 2-hour intervals, then 100 mg every 6-8 hours for first 24 hours.
Adults: 200-800 mg twice daily orally, starting at 200 mg twice daily, increasing by 200 mg/day weekly to maintenance.

Terminal half-life: 7-42 hours (mean 22 hours) in adults; dose-dependent due to saturable metabolism. Steady-state reached in 7-10 days.
Terminal elimination half-life is 20–30 hours in adults with normal renal function; prolonged to 40–60 hours in moderate to severe renal impairment (CrCl <50 mL/min), requiring dose adjustment.
Renal: 70% as metabolites (mainly HPPA glucuronide and sulfate), 5-10% as unchanged drug. Fecal: 30% (minor).
Renal excretion of unchanged drug accounts for approximately 70% of elimination, with 30% metabolized hepatically; metabolites are also renally excreted. Fecal elimination is minimal (<5%).
